Benefits of technology

[0012] It is an aim of the invention to achieve a novel device for helping sportsmen improve their skills by providing information on the repeatability of a motor act, especially a two-phase act such as a golf swing, that is frequently needed in the sport they go in for.

Problems solved by technology

For a golf trainee, it may be frustrating if several professional have different, probably opposing, views of the pros and cons of his or her shots.
What is difficult to exactly evaluate by visual observation of the golfer, is the temporal progression of the swing and especially the similarity of two or more swings.
In addition, hiring of a personal trainer having a suitable video equipment is very expensive, and the video equipment is difficult to carry.
However, such solutions usually change the properties of the club, whereby the measurement results may be unreliable.
In monitoring the swing as a whole, or increasing or analyzing the attained muscle memory needed in golf, the present solutions are more unfavorable.
If one or some of the preceding factors, for example, are irregular, the whole swing, and ultimately the flight path of the ball becomes unpredictable.
There are no known devices or methods which can be used for automatically and objectively analyzing the swing of a golfer in order to assist the golfer to improve his or her skills as a golf player.

example 1

[0084] A test set of 10 wings of 12 different golfers was performed in order to illustrate the capabilities of the present device and method. Two swing properties were chosen to be monitored, namely the duration of the backswing (property 1) and the duration of the downswing (property 2). Table 1 shows the mean values (μ) and standard deviations (σ) of the results. Also the handicaps of the golfers are shown.

example 2

[0087]FIG. 5 shows a graph of predicted handicap values with relation to official handicap values of 32 players. The official hcp is shown on the horizontal axis and the hcp-scaled swing index number obtained from a device (forecast) is shown on the vertical axis. Each of the players were asked to perform six as similar swings as possible. The swing index number was obtained with a wristop device using the principles described in this document.

[0088] The average predicted hcp of the players was 28 (st. dev. 20), the average actual hcp being 25 (st. dev. 16). The correlation factor between the predicted and actual hcp values was 0. 8. The correlation can be considered really high, taking into account that the number of repetition was only six.

Abstract

The invention relates to a portable device and a method for monitoring the performance a sportsman performing a plurality of motor acts, such as golf swings. The device comprises at least one sensor providing an output signal, the sensor being responsive to body movements of the sportsman. A signal processing unit is used for extracting data on the course of each of the plurality of motor acts from the sensor output signal, and a computing unit is used for determining, based on the data on the course of the plurality of motor acts, at least one characteristic number describing the repeatability of the motor act. By the means of the invention, the handicap number of the golfer can be predicted with good accuracy by monitoring several his or her subsequent swings.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to golfing. In particular, the invention relates to a device for analyzing and developing skills of a player. The invention also concerns a method for analyzing the performance of the player during training or playing. [0003] 2. Description of Related Art [0004] Golf is based on one's ability to predict the trajectory of a ball in response to a certain combination of swing and club. Swings of golfers are traditionally analyzed either by naked eye during the hit or by recording the swings using video equipment and analyzing them afterwards. In both cases, for a proper analysis of the pros and cons of the swing, a professional golf trainer is usually needed. Naked-eye and video-based evaluation of swings suits well for discerning major faults in, for example, the stance and alignment of the golfer and the movement of the body of the golfer during the swing. The results of such evaluation are also...
